Product Description:
The 8JSA22.E5B35D700-0 synchronous motor is produced by B & R Automation as part of the 8JS Synchronous Motors series. In factory automation, the motor supplies controlled rotary motion for positioning axes and continuous-duty drives in machinery. Integrated feedback supports closed-loop servo operation by allowing the drive to monitor shaft position and correct motion errors. The motor combines the electrical characteristics of the 8JS platform with frame size 2 and frame length 2, making it suitable for medium-torque stages that require a compact mounting depth.
The thermal design relies on self-cooling, so airflow over the stator housing dissipates heat without an external fan. An optical feedback unit provides an angular precision of ±60 arcsec, while absolute position is measured with 13-bit single-turn and 12-bit multiturn resolution. The encoder has a storage capacity of 4096 revolutions and communicates through an Optical EnDat 2.1 interface, enabling digital diagnostics and automatic parameter transfer. The motor supports flange mounting, which provides consistent alignment when it is attached to a compatible gearbox or machine surface. This mounting arrangement also permits direct face attachment without requiring a separate foot-mounted base.
Power and feedback lines exit through an angled swivel connector, allowing the cable set to be rotated for strain relief in tight enclosures. The encoder’s multiturn capability retains absolute position data across startups, allowing the controller to resume position tracking after power has been disconnected. Torque is transferred through a keyed shaft, which provides positive engagement with couplings or pulleys without relying solely on clamping force. The motor does not include a holding brake, so the drive must provide static torque when the shaft needs to remain fixed while power is available. An internal oil seal limits lubricant migration toward the encoder chamber and helps protect the feedback components during operation.
